MACHINE FOR MAKING COYRD OR TWINE.

SPECIFICATION 'forming part of Letters Patent No. 373,385, dated November 15, 1887.

Application tiled August l1, i886. Serial No. 210,655. (No model.)

To all whom, it may concern:

Be it known that I, GEORGE L. BRowNELL, a citizen of the United States, residing at Worcester,in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Machines for Making Cord or Twine, of which the following is a specilication, accompanied by drawings illustrating a twisting-machine embodying my invention. y

My invention has for its object to produce ar cord or twine in which all the component strands shall be ofequal length and evenlyi laid upon the outside of the cord, and Iattain these results by means of mechanism constructed and arranged as hereinafter described, and set forth in the claims. Y

In the drawings, Figure l is a front View of a portion of a twisting frame or machine .embodying my invention. Fig. 2 represents a vertical sectional View of the spoolsstand with one of the spools in position on the stand, and also an elevation of the water-reservoir and die. Fig. 3 is a top view of the spool-stand and die with a part of the spools in position. Fig. 4 is a sectional view of the water-reservoir. Fig. 5 is a detached viewof the die; and Fig. 6 represents, on an enlarged scale, a portion of the spool-supporting stand.

Similar letters refer to similar parts in the several views.

It is usual to place several sets of twisting mechanisms in a singleframe; but as each is a duplicate of the others in construction'and operation I have shown in the accompanying drawings but one twisting mechanism and a portion of the supporting-frame.

Referring to Fig. l, A denotesthe frame, B, the lower rail, and D the upper rail, between which and the upper horizontal portion ofthe frame AI pivot the revolving head or twisting mechanism proper. The cord to be twisted is taken through the tube a, held rigidly in the upper rail, D, and forming the lower pivot, about which the. head revolves.

The cord is carried around the two stretchingdrums b b, and is wound upon the reel c. I have not described in detail the operation of this part of the machina as it `forms no part of my present invention, and is fully set forth in my application for Letters Patent, Serial No. 139,350., and also in the patent, No.286,258, granted to me on the 9th day of October, A.

D. 1883. To the lower rail, B, I attach a spool-supporting stand consisting ofthe coneshaped base C,with a vertical spindle, E, upon which is placed the circular creel E', resting upon a collar, d, attached by the set-screw d', permitting the position of the creel E to be varied vertically upon the spindle E.

f. In the inner row, e, I place the spool-spin dlesc, and in the outer row, f, the guide Spindles or pins f each spindle of both series of spindles being held in place by a collar resting on the upper surface of the creel andthe nut e2, screwed against the under surface of the creel. The enlarged base C of the stand rests upon the three equidistant feet or legs C', which enable the stand to be made plumb and all the stands in the frame to be brought at the same level by filing one or more ofthe feet G. F denotes the strands to be twisted, and F the spools.

tance below the top of the basin G, forming an upper inclosed chamber, g', containing water, and a lower compartment, g2. A tube, g3, extends from the partition g to within a short distance of the bottom of the basinG,with its lower end closed by the step-valve g4. When the reservoir is placed in the position shown in the drawings, the valve g4 is raised by being brought in contact with the bottom of the basin G, allowing water to flow from the upper f' chamber, g', into the basin G and the lower compartment, g2, and through the pipe Ginto In the l creel E are two rowsof concentric slots, eand the water-cups, as hereinafter described. The 9 5 flow of water will continue until the water in the basin rises high enough to close the lower end of the tube g3 to the admission of air to the waterchamber g. An' opening, y, is made through the wall of the reservoir G3, to admit air above the water in the lower. compartment, g2.

To the basin G, I attach a pipe, G4, which is held in the clamp G5, tightened by thethumbscrew g5. From the pipe G', which runs along beneath the lower rail, B, a pipe, Gl, is carried up through each hollow stand C and spindle E. The pipe GT is serew-threaded at the top to receive the nut GS, whose under side is ehamfered and enters the end ol' the hollow spindle E, thereby centering thc pipe GT with the spindle E, and drawingthc tlange G of the pipe against the under side of the .lower rail, B, and binding the stand C tirmly against the rail B. Upon the projecting end of the screwthreaded pipe Gl, I screw the circular watereup H, screwing it down on thc vnut Gi, and forming a water-tight joint.

The die I is a small circular plate, having a central hole, i, the size of the twisted cord. lt is supported from the sleeve I', attached to the tube a by a set-screw, 1V, which allows the die to be adjusted with reference to the watercup H, and also the depth of its immersion in the water to be Varied. \Vatcr is maintained in the cup H by adjusting the lheight ot' the basin G, by means ot` the clamp Gi", so the water-line required to seal the end ofthe tube y shall correspond with the desired water-line of the cups H. \Vhen it is desired to withdraw the water from the watcr-cups, the basin G is lowered so the water will run back into the lower compartment, g'.

Each of the strands F is carried around its corresponding guide-pin and over the edge of the circular watcrcup H, beneath the dic-plate I, and through its central opening, t', and the tube a to the twisting mechanism, by whose rotation the strands are twisted into the cord F2, and wound upon the reel c.

The strands F are carried over the edge ot' the water-cup H, and are presented tothe die at nearly right angles to the axis of the die, the tension upon each strand tending to hold it against the inner edge ol" the die and preventing any of the strands from being` drawn into the center ofthe cord, and thereby forming a core, around which the remaining strands will be twisted. By holding the strands against the inner surface of the die they are maintained at all times at an equal distance from the axis of rotation, and as the cord is twisted they become laid upon the outside, thereby securing a uniform length of all the strands in any given section of cord. This is an advantage in any twisted cord, and particularly in some kinds, such as that employed in wax-thread boot and shoe sewing machines, where the process of waxing the thread draws the slacker strands, forming loops which interfere with the process of sewing.

rlhe under surface of the die I is brought into contact with the surface of the water in the cup I-I, which secures the wetting of the strands as they pass beneath the die. It' the die is barely in contact with the water, the strands will be moistened but slightly; but the amount of water absorbed by the strands may be increased by loosening the set-screw i and lowering the die into the water and increasing the time the strand is held beneath the water as it passes under the die. The die may be raised entirely free from the watercup by sliding the sleeve I upwardly on the tube a, allowing the die to be cleared of lint or knots which may obstruct its passage.

The spools F/ are arranged at equal distances upon the creol E, and within as small space as will ai'fordroom enough for changing thcspools. I secure sntiieient length ofstrand between the watercup and the spool, and thereby prevent thc strand from being drawn olf the spool at too acute an angle, by placing a row ot equidistant pins, f', outside the row of spools, around which the strands are carried, bringing each strand in convenient position outside the spools to be reached by the attendant. rIhe creel E' is capable of being rotated around the spindle E so it can be freely turned to bring any ot the strands upon the outer side. The occasional turning of the crecl for the purpose of mending broken ends and replacing the spools will so change the position ol' the strands as they move across the edge of the water-cup as to prevent its becoming worn into grooves by the continued friction of the strand in one path.

I am aware that strands to be twisted have been carried through water. Such I do not claim, broadly; neither do I claim the use of a die in a twisting-machine, as they have long been in use.

Vhat I do claim, and desire to secure by Letters Iatent, is
